Updating chapters of NNR

The new edition of NNR (NNR2022) will include an update of all 42 chapters in NNR2012. In addition, new chapters may be developed for topics of specific importance for public health in the Nordic or Baltic countries. In NNR2022, there will be an increased focus on foods and dietary patterns as well as the integration of overweight and obesity, and sustainability and environmental issues.

An in-depth review of the principles and methodology for updating NNR has been published as two separate chapters, one focusing on the overall principles and methodology for updating NNR and one focusing on the methodology for conducting systematic reviews.

Call for experts

The NNR2022 update project will engage several scientific experts across the Nordic countries. Experts will be involved in different parts of the NNR project from conducting and reviewing systematic literature reviews to writing and reviewing chapters. A broad range of experts will be engaged, from methodology experts (e.g. statisticians, librarians) to researchers with experience with nutrients- and food-based dietary guidelines. Both experienced and young researchers are encouraged to apply. Experts performing systematic reviews will be organized in virtual NNR-SR Centre.

To become an NNR expert, you had to submit an application form including contact information, area of expertise and preferred way(s) of contributing (i.e. as a systematic review expert, chapter expert and/or peer-reviewer of systematic reviews or NNR chapters). You had to also provide information on which topics (i.e. nutrient, food, food compound) suits your competence. As an NNR expert you might be engaged in the update of several chapters. The application must be supported by an academic CV.

Received applications was reviewed by the NNR2022 Committee and evaluated based on personal skills and competence related to the different tasks. Suitable candidates was contacted.

The public call was open until all chapter authors and referees have been appointed. The call is now closed.

De novo Systematic Reviews

The NNR2022 Committee has prioritized 9 PI/ECOTSS for de novo systematic reviews (SRs). The prioritisation of PI/ECOTSS was decided in a modified Delphi process. The protocols will be published in PROSPERO and available for the public. All SRs will be conducted by the NNR-SR Centre.

The nine topics prioritised for SR are:

  1. Plant protein intake in children and body growth
  2. Pulses/legumes intake and cardiovascular disease and type 2 diabetes
  3. Plant protein intake in adults and atherosclerotic/cardiovascular and disease type 2 diabetes
  4. Vitamin B12 and vitamin B12 status in susceptible groups
  5. Fat quality and mental health
  6. Intake of white meat (no consumption vs high consumption and white meat replaced with red meat) and all-cause mortality, type 2 diabetes and risk factors
  7. Intake of n-3 LPUFAs from supplements during pregnancy and asthma and allergies in the offspring 
  8. Intake of nuts and CVD and type 2 diabetes in adults
  9. Dietary fibre intake (high vs low) in children and bowel function

The results of this process is described in a scientific article and submitted to Food & Nutrition Research. The article is now accepted by the journal and will be published shortly. Høyer A, Christensen JJ, Arnesen EK, Andersen R, Eneroth H, Erkkola M, et.al. The Nordic Nutrition Recommendations 2022 – Prioritization of topics for de novo systematic reviews. Food Nutr Res. 2021.
